A full deck. The spectator freely cuts into three piles and the top cards are turned face up. The cards are then divided into two halves and dealt one by one—only the cards cut by the spectator match perfectly.
Even more, the unmatched cards are freely cut and perfectly shuffled. The deck is split into two piles, the spectator chooses one pile and cuts it into four packets. The cards cut by the spectator still match the corresponding cards in the other pile.
For the complete routine, watch the video performance.
